in LS closed shell nuclei plus or minus one nucleon, as
1. LS-closure, no spin-orbit partners on both sides of the Fermi surface, therefore the magnetic moment operator can not couple to magnetic resonance.
➢ Because the single particle state can couple to more
complicated 2p-1h configurations and there are mesons exchange corrections caused by the nuclear medium effect, the configuration mixing provide a better foundation to describe the observed values . The mean field may not be expected to describe the magnetic moment well.
